Tropical Cyclone Three Day Outlook for the Coral Sea
Issued at 2:30 pm EST on Sunday 1 February 2015
for the period until midnight EST Wednesday 4 February 2015.

Existing Cyclones in the Eastern Region:

Nil.

Potential Cyclones:

Tropical Cyclone Ola, situated well offshore of the Queensland east coast (west
of New Caledonia) is expected to move in a general southwards direction over
the next couple of days and may enter the region on Tuesday. Tropical Cyclone
Ola should be on a weakening trend around the time it approaches the region,
though for the latest information on this system refer to the Fiji
Meteorological Service website at http://www.met.gov.fj.

There are no other significant lows in the region and none are expected to
develop over the next few days.

Likelihood of a tropical cyclone in the Eastern Region on:
Monday Very low
Tuesday Low
Wednesday Low

NOTES: The likelihood is an estimate of the chance of each system being a
tropical cyclone in the Region for each day.
Very Low: less than 5% Moderate: 20 to 50%
Low: 5% to 20% High: over 50%

The area of coverage for this outlook is the Coral Sea and northern Tasman Sea
west of 160E.

REMARKS:
010900Z POSITION NEAR 20.8S 162.3E.
TROPICAL CYCLONE 10P (OLA), LOCATED APPROXIMATELY 233 NM WEST-
NORTHWEST OF NOUMEA, NEW CALEDONI, HAS TRACKED SOUTHWARD AT 08
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS THE LOW-LEVEL CIRCULATION CENTER CONTINUING TO
CONSOLIDATE BUT IS OBSCURED BY A CENTRAL DENSE OVERCAST FEATURE. A
010428Z SSMI MICROWAVE IMAGE SHOWS IMPROVED BANDING WITH THE DEEPEST
CONVECTION LOCATED IN THE SOUTHWESTERN QUADRANT OF THE SYSTEM. THE
INITIAL POSITION IS BASED ON THE ABOVE IMAGERY WITH GOOD CONFIDENCE.
OVER THE PAST 24 HOURS, TC OLA HAS UNDERGONE RAPID INTENSIFICATION
FROM 45 KTS TO AN ASSESSED INTENSITY OF 80 KNOTS, BASED ON DVORAK
INTENSITY ESTIMATES FROM ALL REPORTING AGENCIES. MODERATE (10 TO 20
KT) VERTICAL WIND SHEAR (VWS) IS OFFSET BY VERY GOOD POLEWARD
OUTFLOW. THE SYSTEM IS CURRENTLY TRACKING TO THE SOUTH ALONG THE
WESTERN EDGE OF A DEEP SUBTROPICAL RIDGE AND IS EXPECTED TO MAINTAIN
THAT TRAJECTORY THROUGH TAU 24. ADDITIONALLY, FAVORABLE UPPER LEVEL
DYNAMICS WILL ALLOW FOR A SLIGHT INCREASE IN INTENSITY. HOWEVER,
BEYOND THIS, EXPECT A RIDGE TO FORM SOUTH OF THE SYSTEM, FORCING TC
10P TO GAIN A MORE WESTWARD COMPONENT. DUE TO THE INCREASED VWS AND
COOLER SSTS, EXPECT TC OLA TO BEGIN TO DISSIPATE BY TAU 48 AND
COMPLETE DISSIPATION BY TAU 96. THERE CONTINUES TO BE A BIFURCATION
IN THE DYNAMIC MODEL GUIDANCE, WITH GFS DRIVEN MODELS CONTINUING TO
FORCE TC 10P SOUTH AHEAD OF THE BUILDING RIDGE, WHICH MAY STILL BE A
POSSIBLE SCENARIO. HOWEVER, ALL MODELS AGREE THAT FURTHER
INTENSIFICATION OF THE SYSTEM, IF ANY, WILL BE MILD BEFORE VWS AND
SSTS CAUSE IT TO DETERIORATE. FOR THE ABOVE REASONS, THE JTWC
FORECAST TRACK IS LAID WITH LOW CONFIDENCE. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 010600Z IS 20 FEET. NEXT WARNINGS AT 012100Z AND
020900Z.//
